Copy of first file to NVX on XRAID2 always fails
I have a NVX with 3 disks of 1GB in XRAID2
each time after a fresh start of the NVX the first file I copy to the NVX stops during the copy
for no reason at all... after a while it fails or picks up again
eg when I use supercopier 2 I get an error message.
once it has failed once, I can transfer files just fine.
anyone else have this problem or does this sound familiar to anyone else?
or even have a solution for it? thx

- Hi
I can access the files on my nas perfectly, and after the first write fails, they also work fine.
from what I read on this page http://www.readynas.com/?page_id=82Added support for 4K sector drives. If you have already installed 4K sector drives with 4.2.11 or earlier, you can replace each disk one by one, allowing it to complete resync, and all your disks will be 4K aligned, and your performance should be on par with similar 512-byte sector drives.
would that mean that I could resync my drives by reinserting them or something?
how can I find out if my drives have 4k or 512B sectors? - Download your logs (Status > Logs > Download all logs) and extract the zip contents. What are the contents of your partition.log?

/dev/sdc4 0 - 0 0 0 Empty - O.K. The third disk /dev/sdc is 4k sector partition aligned. The other two are not. So you could hot-remove (remove while NAS is on) one disk at a time, wait a bit, then hot-add (add while NAS is on) wait for resync to complete and volume status to return to redundant then move onto next disk.
- so I need to do that for all the disks right?
and does it matter what disk I remove add first?
what is the chance this would mess up my system?
btw thx for the support, netgear support was not much help.
and how do you know that the last one is 4k sector aligned, because of the entries the partition table can hold? abeman wrote: so I need to do that for all the disks right?
No just /dev/sda and /dev/sdb. /dev/sdc (probably disk 3) is already 4k sector partition aligned. One of the logs would indicate which is which disk.abeman wrote:

Only if one or more of your disks is failing.abeman wrote:

If a disk is failing, yes.abeman wrote:

Well I'm a user like you, so I don't mind, except my personal preference would be to use supported disks. Disks not on the compatibility list may/may not work.abeman wrote:

Why you might want to factory reset a x86 ReadyNAS
